manufacture of linen in Scotland, and that of coarse woollens in the West Riding of Yorkshire, are growing manufactures, of which the produce is generally, though with some variations, increasing both in quantity and value. Upon examining, however, the accounts which have been published of their annual produce, I have not been able to observe that its variations have had any sensible connection with the dearness or cheapness of the seasons. In 1740, a year of great scarcity, both manufactures, indeed, appear to have declined very considerably. But in 1756, another year of great scarcity, the Scotch manufacture made more than ordinary advances. The Yorkshire manufacture, indeed, declined, and its produce did not rise to what it had been in 1755 till 1766, after the repeal of the American Stamp Act. In that and the following year it greatly exceeded what it had ever been before, and it has continued to advance ever since.
The produce of all great manufactures for distant sale must necessarily depend, not so much upon the dearness or cheapness of the seasons in the countries where they are carried on as upon the circumstances which affect the demand in the countries where they are consumed; upon peace or war, upon the prosperity or declension of other rival manufactures, and upon the good or bad humour of their principal customers. A great part of the extraordinary work, besides, which is probably done in cheap years, never enters the public registers of manufactures. The men servants who leave their masters become independent labourers. The women return to their parents, and commonly spin in order to make clothes for themselves and their families. Even the independent workmen do not always work for public sale, but are employed by some of their neighbours in manufactures for family use. The produce of their labour, therefore, frequently makes no figure in those public registers of which the records are sometimes published with so much parade, and from which our merchants and manufacturers would often vainly pretend to announce the prosperity or declension of the greatest empires.
Though the variations in the price of labour not only do not always correspond with those in the price of provisions, but are frequently quite opposite, we must not, upon this account, imagine that the price of provisions has no influence upon that of labour. The money price of labour is necessarily regulated by two circumstances; the demand for labour, and the price of the necessaries and conveniences of life. The demand for labour, according as it happens to be increasing, stationary, or declining, or to require an increasing, stationary, or declining population, determines the quantity of the necessaries and conveniencies of life which must be given to the labourer; and the money price of labour is determined by what is requisite for purchasing this quantity. Though the money price of labour, therefore, is sometimes high where the price of provisions is low, it would be still higher, the demand continuing the same, if the price of provisions was high.
It is because the demand for labour increases in years of sudden and extraordinary plenty, and diminishes in those of sudden and extraordinary scarcity, that the money price of labour sometimes rises in the one and sinks in the other.
In a year of sudden and extraordinary plenty, there are funds in the hands of many of the employers of industry sufficient to maintain and employ a greater number of industrious people than had been employed the year before; and this extraordinary number cannot always be had. Those masters, therefore, who want more workmen bid against one another, in order to get them, which sometimes raises both the real and the money price of their labour.
The contrary of this happens in a year of sudden and extraordinary scarcity. The funds destined for employing industry are less than they had been the year before. A considerable number of people are thrown out of employment, who bid against one another, in order to get it, which sometimes lowers both the real and the money price of labour. In 1740, a year of extraordinary scarcity, many people were willing to work for bare subsistence. In the succeeding years of plenty, it was more difficult to get labourers and servants.
The scarcity of a dear year, by diminishing the demand for labour, tends to lower its price, as the high price of provisions tends to raise it. The plenty of a cheap year, on the contrary, by increasing the demand, tends to raise the price of labour, as the cheapness of provisions tends to lower it. In the ordinary variations of the price of provisions those two opposite causes seem to counterbalance one another, which is probably in part the reason why the wages of labour are everywhere so much more steady and permanent than the price of provisions.
The increase in the wages of labour necessarily increases the price of many commodities, by increasing that part of it which resolves itself into wages, and so far tends to diminish their consumption both at home and abroad. The same cause, however, which raises the wages of labour, the increase of stock, tends to increase its productive powers, and to make a smaller quantity of labour produce a greater quantity of work. The owner of the stock which employs a great number of labourers, necessarily endeavours, for his own advantage, to make such a proper division and distribution of employment that they may be enabled to produce the greatest quantity of work possible. For the same reason, he endeavours to supply them with the best machinery which either he or they can think of. What takes place among the labourers in a particular workhouse takes place, for the same reason, among those of a great society. The greater their number, the more they naturally divide themselves into different classes and subdivisions of employment. More heads are occupied in inventing the most proper machinery for executing the work of each, and it is, therefore, more likely to be invented. There are many commodities, therefore, which, in consequence of these improvements, come to be produced by so much less labour than before that the increase of its price is more than compensated by the diminution of its quantity.
Chapter 9 Of the Profits of Stock
The rise and fall in the profits of stock depend upon the same causes with the rise and fall in the wages of labour, the increasing or declining state of the wealth of the society; but those causes affect the one and the other very differently.
The increase of stock, which raises wages, tends to lower profit. When the stocks of many rich merchants are turned into the same trade, their mutual competition naturally tends to lower its profit; and when there is a like increase of stock in all the different trades carried on in the same society, the same competition must produce the same effect in them all.
It is not easy, it has already been observed, to ascertain what are the average wages of labour even in a particular place, and at a particular time. We can, even in this case, seldom determine more than what are the most usual wages. But even this can seldom be done with regard to the profits of stock. Profit is so very fluctuating that the person who carries on a particular trade cannot always tell you himself what is the average of his annual profit. It is affected not only by every variation of price in the commodities which he deals in, but by the good or bad fortune both of his rivals and of his customers, and by a thousand other accidents to which goods when carried either by sea or by land, or even when stored in a warehouse, are liable. It varies, therefore, not only from year to year, but from day to day, and almost from hour to hour. To ascertain what is the average profit of all the different trades carried on in a great kingdom must be much more difficult; and to judge of what it may have been formerly, or in remote periods of time, with any degree of precision, must be altogether impossible.
But though it may be impossible to determine, with any degree of precision, what are or were the average profits of stock, either in the present or in ancient times, some notion may be formed of them from the interest of money. It may be laid down as a maxim, that wherever a great deal can be made by the use of money, a great deal will commonly be given for the use of it; and that wherever little can be made by it, less will commonly be given for it. According, therefore, as the usual market rate of interest varies in any country, we may be assured that the ordinary profits of stock must vary with it, must sink as it sinks, and rise as it rises. The progress of interest, therefore, may lead us to form some notion of the progress of profit.
By the 37th of Henry VIII all interest above ten per cent was declared unlawful. More, it seems, had sometimes been taken before that. In the reign of Edward VI religious zeal prohibited all interest. This prohibition, however, like all others of the same kind, is said to have produced no effect, and probably rather increased than diminished the evil of usury. The statute of Henry VIII was revived by the 13th of Elizabeth, c. 8, and ten per cent continued to be the legal rate of interest till
